3. The computer-implemented method of claim 2, wherein, in response to that the sum of the selected one or more of the plurality of reserve balances is greater than the transaction amount, a change amount is added to the first inward remittance balance after the transaction is implemented, and wherein the change amount is a difference between the sum of the selected one or more of the plurality of reserve balances and the transaction amount.

5. The computer-implemented method of claim 1, wherein a balance of the blockchain account of the receiver comprises a second inward remittance balance, and a commitment of the second inward remittance balance is recorded in the blockchain; and wherein the commitment of the transaction amount is added to the commitment of the second inward remittance balance after the transaction is implemented.

6. The computer-implemented method of claim 5, wherein the commitment of the second inward remittance balance is an encryption of the second inward remittance balance based on an inward remittance balance random number.

13. The apparatus of claim 12, wherein, in response that the sum of the selected one or more of the plurality of reserve balances is greater than the transaction amount, a change amount is added to the first inward remittance balance after the transaction is implemented, and wherein the change amount is a difference between the sum of the selected one or more of the plurality of reserve balances and the transaction amount.

15. The apparatus of claim 11, wherein a balance of the blockchain account of the receiver comprises a second inward remittance balance, and a commitment of the second inward remittance balance is recorded in the blockchain; and wherein the commitment of the transaction amount is added to the commitment of the second inward remittance balance after the transaction is implemented.
